Tweaks for Special:Newpages:
* (bug 13756) Don't show the form and navigation links if the page is included
* Readded options overriding with $par, useful when the page is included
* Override limit and offset in pager so that they are also modified if they are specified in $par (when page is included)
* Force NewPagesPager::getTitle() to return the title object of Special:Newpages even if included, navigation bar was linking to the included page, wich might not a very good idea sometimes
* Fix some whitespaces
